Overview
This manual is designed to provide you with enough information to
get your system up and running. Use this manual if you are
knowledgeable about the products, but may have not used one or
more of the products for a period of time. The information provided
is geared towards “jogging your memory.”
About the Application
This manual presents an example application that uses a PLC-5
processor to control the temperature in a system. Using a
PanelView 550, you can set the desired temperature and view the
actual system temperature. A J-Type thermocouple connected to a
thermocouple input module senses the temperature of the system.
The PLC-5 processor controls a digital output module, using timed
proportional output (TPO), which pulses an ac signal to the
heating device.

Tip
The PanelView 550 allows you to view and change the temperature of a system. The
PanelView 550 acts as a window into your process" by allowing you to view and change
the temperature of the system. It reads the temperature from the processor's memory and
writes new set points into the processor's memory.

(see the Tip of step 5 on page 27), then you must:
1. Skip this section, and perform a direct download through the serial
port of the PV550 terminal. See the PanelView 900 Configuration
Software User Manual, publication number 2711815 for instructions
about how to do so.
2. Go to page 4-4 to automatically configure the I/O scan list.
